Review on Breath Easy With LANGRIA'S Compact Air Purifier - 3 Stage Filtration, True HEPA, Portable, Powerful And Silent - White (Model:EPI080) by Adam Walsh

First of all, you cant find replacement filters. I have a feeling filters for different brands might work but I havent tried it. But I think the most important thing is, unless you are on the highest setting which is very loud, this little guy doesnt filter much. :/ i keep mine on the middle setting and dust builds up around it!
